The Civil engineers, Architects, Builders, and Contractors agree that the river sand, which is available today, is deficient in many respect. It does content very high silt fine particles (as in case of Filter sand). Presence of other impurities such as coal, bones, shells, mica and silt etc makes it inferior for the use in cement concrete.

Sand is the second most traded raw material after water. Since the demand for sand – among others in the concrete industry – is growing faster than suitable sand resources can be found, sand is instead produced from gravel or transported over long distances. Rhewum has developed a solution to process sand mobile and therefore directly on site.

The use of manufactured sand makes sense from various perspectives. First, manufactured sand is more uniform in structure compared with natural sand. It also has an advantage when it comes to concrete production, because manufactured sand is less needed in the concrete mix by a margin of 5 to 20% compared with natural sand to fill the voids

Crushed sand can be of coarser and angular texture. This can lead to more water and cement requirement to achieve the expected workability. Manufactured sand can contain larger amounts of micro fine particles than natural sand, This can affect the strength and workability of the concrete. We are also using M-sand for current project.
